我正在尝试通过VBA提取雅虎财经分析师的价格目标(例如:分析师数量、最高、最低、平均、当前)
但我无法通过 .getelementsbyclassname/.getelementbyID 提取其中任何一个。
这是我的代码:
Sub Analysis_import()
Dim website As String
Dim request As Object
Dim response As String
Dim html As New HTMLDocument
Dim price As Variant
website = "https://finance.yahoo.com/quote/AAPL/analysis?p=AAPL"
Set request = CreateObject("MSXML2.XMLHTTP")
request.Open "get", website, False
request.setRequestHeader "If-Modified-since", "Sat, 1 Jan 2000 00:00:00 GMT"
request.send
response = StrConv(request.responseBody, vbUnicode)
html.body.innerHTML = response
price = html.getElementsByClassName("Fz(m) D(ib) Td(inh)").innerText
Debug.Print price
End Sub
问题是什么?非常感谢!
您希望从该站点获取的字段是动态生成的,因此您无法使用
HTMLDocument
解析器获取它们。如果您想使用 tag
、id
、class
等定位字段,您的选项将是 IE
或 Selenium
。
但是,好消息是原始 json 内容中的某些脚本标记中提供了必填字段。因此,即使您坚持使用 xmlhttp
请求,您也可以使用
vba json converter或正则表达式来处理它们。以下脚本基于正则表达式。
Sub GrabAnalysisInfo()
Const Url As String = "https://finance.yahoo.com/quote/AAPL/analysis?p=AAPL"
Dim sResp$, sHigh$, currentPrice$
Dim analystNum$, sLow$, tMeanprice$
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", Url, False
.setRequestHeader "User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36"
.send
sResp = .responseText
End With
With CreateObject("VBScript.RegExp")
.Pattern = "numberOfAnalystOpinions[\s\S]+?raw"":(.*?),"
If .Execute(sResp).count > 0 Then
analystNum = .Execute(sResp)(0).SubMatches(0)
End If
.Pattern = "targetMeanPrice[\s\S]+?raw"":(.*?),"
If .Execute(sResp).count > 0 Then
tMeanprice = .Execute(sResp)(0).SubMatches(0)
End If
.Pattern = "targetHighPrice[\s\S]+?raw"":(.*?),"
If .Execute(sResp).count > 0 Then
sHigh = .Execute(sResp)(0).SubMatches(0)
End If
.Pattern = "targetLowPrice[\s\S]+?raw"":(.*?),"
If .Execute(sResp).count > 0 Then
sLow = .Execute(sResp)(0).SubMatches(0)
End If
.Pattern = "currentPrice[\s\S]+?raw"":(.*?),"
If .Execute(sResp).count > 0 Then
currentPrice = .Execute(sResp)(0).SubMatches(0)
End If
End With
Debug.Print analystNum, tMeanprice, sHigh, sLow, currentPrice
End Sub
我尝试使用VBA脚本,但如果为假,则.Execute(sResp).count > 0,因此它无法从雅虎财经获取任何数据(tMeanprice、slow、shigh)。有可行的脚本吗?
